chore(core): remove sha1 from regular FW

This commit removes the SHA-1 hashing function from the regular Trezor firmware. SHA-1 is an old, weak hash algorithm that is no longer considered secure for sensitive uses. The change deletes the code that exposes SHA-1 to apps running on…

refactor(crypto): pass static public key to `noise_xxpsk3_*_init()`

This commit changes how a cryptographic library sets up secure connections. Previously, the code automatically calculated the public key from the private key. Now, the caller must provide the public key directly. This is a code-quality ref…

refactor(crypto): change order of parameters

This commit simply reorders the arguments of an internal function called dh() and updates every place that calls it. The actual math and security behavior are unchanged; it is a code cleanup with no security effect.

refactor(crypto): prefix enums

This commit simply renames two groups of internal status labels (called enums) in the Trezor firmware's cryptographic code. The old names like WAITING_FOR_REQUEST1 were shared between two different parts of the code, so the developer gave …

fix(crypto): prevent calling `memzero(NULL, ...)`

This commit fixes three places in the Trezor firmware's cryptographic code where a memory-clearing function could be called with a NULL pointer. In practice, passing NULL to memzero is harmless on Trezor's platform (it does nothing), but i…

refactor(crypto): return remote static key from `noise_xxpsk3_*_handle_*()`

This commit is a code cleanup (refactor) for the cryptographic handshake code used in Trezor devices. It changes how the other party's long-term public key is returned to the caller: instead of storing it inside an internal state structure…

refactor(xtask): rename ProjectProfile to ProjectConfig

This commit is a simple rename from 'ProjectProfile' to 'ProjectConfig' in two Rust source files. It only changes variable names, struct names, and error messages. There is no change to program logic, security behavior, or how data is hand…

refactor(xtask): introduce ResolvedBuildArgs

This commit is a straightforward internal code refactor in Trezor's build tooling. It introduces a new ResolvedBuildArgs structure that centralizes default values for command-line build options before they are used. There is no change to u…

refactor(xtask): make build args tristate

This commit is a straightforward internal refactor of the Trezor firmware build tool's command-line argument handling. It changes many on/off flags from plain booleans to optional booleans so they can explicitly be set to true, false, or l…

refactor(xtask): introduce build options

This commit is a straightforward internal code reorganization in Trezor's build tooling. It moves build-option definitions from one Rust source file to a new module and adds the ability to load those options from a configuration file. Ther…

feat(xtask): introduce build presets

This commit is a developer tooling change for the Trezor firmware build system. It introduces 'build presets'—named configuration bundles stored in TOML files—so developers can select common build settings with a single command-line flag i…

feat(xtask): upgrade manifest.yaml for tf-tools 0.3.0

This commit is a routine update to a build-system manifest file used by Trezor's internal tooling. It reorganizes and re-labels feature flags (for example, moving options between 'Features', 'Debugging', and 'Signing' groups and simplifyin…

feat(core): add tf-tools 0.3.1+ configuration file

This commit adds a single configuration file for a Trezor developer tool (a VS Code extension). It only points the tool to existing folders in the repository and contains no executable code, no secrets, and no changes to firmware behavior.…

refactor(xtask): rename ResolvedBuild to ResolvedBuildFeatures

This commit is a simple internal code cleanup: it renames a Rust data structure called ResolvedBuild to ResolvedBuildFeatures and updates the places that use it. There are no functional changes, no security fixes, and no changes to how the…

fix(core): fix up clippy warnings in storage.rs

This is a tiny code cleanup commit that replaces two calls to `ptr::null()` with Rust's `unwrap_or_default()` to silence automated Clippy lint warnings. It does not change what value is produced (still a null pointer when no salt is provid…

refactor(xtask): simplify dependencies

This commit is a straightforward internal code cleanup in Trezor's build tooling. It moves a data structure and two helper methods from one Rust source file to another and updates callers accordingly. There is no change to user-facing beha…

docs: add xtask documentation

This commit only adds documentation. It updates the table of contents and adds a new markdown page plus a diagram explaining the project's 'xtask' build helper. No code, build scripts, or firmware logic was changed, so it cannot introduce …

feat(xtask): introduce project-toml build-options

This commit is a build-system refactoring for Trezor firmware. It moves the mapping of command-line build options to Rust/cargo features out of hard-coded Rust logic and into per-project TOML files. It also adds a small change so debug bui…

ci(core): fix nightly ARM emulator filename

This commit fixes a filename-renaming step in the project's automated nightly build pipeline. It ensures ARM64 emulator files get the correct name expected by another testing tool. There is no change to the actual Trezor firmware code, dev…

chore(vendor): avoid micropython submodule noise in git status

This is a routine housekeeping change to reduce clutter in Git's status output for a third-party component (the MicroPython submodule). There is no indication it changes any code that runs on the Trezor device or affects security.
